How to add applet in servlet ?

I've made one applet in java swings.
How can i add that applet in my servlet program ?

Make sure the applet is in a publicly visible URL (ie not in the WEB-INF directory) and generate the HTML described here [Plugin Developers Guide|http://java.sun.com/j2se/1.5.0/docs/guide/plugin/developer_guide/using_tags.html] .

Maybe you changed the key /apps/metacity/general/mouse_button_modifier in gconf-editor. I had changed it to <Super>, resetting it to the default (<Alt>) made Alt+Right-Click work. (at least, for some time after the session starts, but it may be an other problem).

Urgent: how to run applet which connected to the servlet?

hi frends:
i have written an applet on the server side and it supposed to pass parameters to my servlet and retrieve some info from the servlet.
i put both applet and servlet under tomcat../WEB-INF/classes. but when i run the applet from the web browser, there is no response from the servlet.
could anyone help me to solve this problem?
one more thing is i know that applet is able to connect to servlet, but how about java application? is it able to do so? if yes, is it also using URLconnection as applet? and how to run it?
i will be very appreciate if anyone can help me... thanx a million.

You can connect to the servlet from an application.There's a URL class in java.net that has an openConnection method. Then cast the return to an HttpURLConnection and use setMethod to set up as a post request.This may be the default if you call setDoOutput(true) on the URLConnection. Then you'll need to get an OutputStream and write properly formatted form POST data to it. It's also possible to encode your data on the URL, even when using the POST method, and this may be easier when doing it programmatically from an application. To send a get request you can append the name-value pair at the end of the url.

How to add scroll function in the applet launched by Java Web Start?

I have Java Web Start installed in order for the applet to launch.The applet size: width:700 height:1000
my compuer resolution:800*600
the applet launched by Java Web Start can only be seen partly,especially height.How to add scroll function in the applet launched by Java Web Start?
Thanks for help.
email:[email protected]

You can very easily add a JScrollPane manually between the Applet and your content. Perhaps it would be beter if javaws did this automatically. In the browser, an applet can be any size. In Java Web Start an applet is directly contained within a JFrame, so it cannot be smaller than the minimum size of a JFrame, or Larger than the max.

How to do Applet/Servlet permanent interactive connection

Hi, I'm modifying an Instant Messaging Application originally implemented under the Applet client/standalone-server scheme that I'm implementing now under the Applet/Servlet scheme using HTTP Tunneling with Object Serialization. But this yet don't work correctly because the connection's flows are closed ever after a Servlet's response to a client request (in this moment are close the connection's flows). I'm using flows of type ObjectInputStream and ObjectOutputStream using Object Serialization with HTTP Tunneling.
this is part of the connection code in the servlet side:
public void doGet (HttpServletRequest request, HttpServletResponse response) throws
ServletException, IOException{
doPost( request, response);
public void doPost(HttpServletRequest request, HttpServletResponse response) throws
ServletException, IOException{
is = new ObjectInputStream(
new BufferedInputStream(request.getInputStream()));
try{
response.setStatus(HttpServletResponse.SC_OK);
out = new ObjectOutputStream (
new BufferedOutputStream (response.getOutputStream ()));
out.writeObject("OK");
out.flush();
// Send the input and output flows to the Thread the Handle the client Connection
newUser(is, out);
} catch(Exception ex){
System.err.println("Exc1: "+ex.toString());
ex.printStackTrace();
Run Method to read client request:
public void run() {
SocketData sd;
while ((sd = readObject()) != null) {
sd.performAction(this);
close();
After a servlet response in the readObject() method the input flow is closed in the reader request of clients and the connection between the applet (client) and servlet is lost.
How to can implement a smarter HTTP Tunneling with permanent interactive connection beetween the Applet and Servlet such as in the Applet /server Standalone connection using TCP/IP Socket connection.
Is possible the use of TCP/IP Sockets in the implementation of HTTP Tunneling with Object Serialization in the Applet/Servlet permanent interactive communication scheme?
some links or code samples?
Please show me the ligth.
Thanks greatly a smarter help.

I'm not sure that I fully understand your problem, but HTTP is a stateless protocol. That means request-response pairs are completely separated from each other.
You should ask yourself if you really need to use HTTP and a servlet or if a raw TCP/IP communication would be a better approach to your problem.

How can my applet communicate with servlet via HTTPS?

hi all,
I'm using jdk1.4.2_03. Tomcat 4.1.27/29.
My applet used to communicate to serlvet/JSP via http protocol. However, I wish to apply SSL in my tomcat standalone. Is there any implication towards my existing applet to servlet codes?
For example,
URL servletURL = new URL("http://www.myhost.com/Shopping");
// open connection between applet and servlet
URLConnection servletConnection = servletURL.openConnection();
servletConnection.setDoOutput(true); // allow connection do output
servletConnection.setDoInput(true); // allow connection do input
servletConnection.setUseCaches(false);
servletConnection.setRequestProperty("Content-Type", "application/octet-stream");
ObjectInputStream input = new ObjectInputStream(servletConnection.getInputStream());
resultset = (Vector)input.readObject(); //get Object from Servlet
input.close();

http://java.sun.com/j2se/1.4.2/docs/api/javax/net/ssl/HttpsURLConnection.html
I never used it though, you can check for some code here:

yeah! i got the related topic at http://www.theserverside.com/tt/articles/article.tss?l=HttpClient_FileUpload. please look it, i am reading it right now and expecting to be reliable for me.
well what i got, when request made by html code(stated above) then all the form fields and file data mixed as binary data and available in HttpServletRequest.getinputstream. and at servlet side we have to use a mutipart parser of DiskFileItemFactory class that automatically parse the file data and return a FileItem object cotaing the actual file data,right?.You can also setup the MultipartFilter in your environment and don't >care about it further. Uploaded files will be available as request attributes in the servlet.is the multipartfilter class file available in jar files(that u suggested to add in yours article) so that i can use it directly? one more thing the import org.apache.commons.httpclient package is not available in these jar files, so where can got it from?
one mere question..
i looked somewhere that when we request for a file from webserver using web browser then there is a server that process our request and after retrieving that file from database it sends back as response.
now i confused that, wheather these webservers are like apache tomcat, IBM's webspher etc those processes these request or there is a unique server that always turned on and process all the request?
because, suppose in an orgnisation made it's website using its own server then, in fact, all the time it will not turned on its server or yes it will? and a user can make a search for kind of information about this orgnisation at any time.
hopes, you will have understand my quary, then please let me know the actual process

How to add a hyperlink to javamail attachment?

Hi friends:
I am writing a mail systems.I can receive email attachment using javamail API. But I don't know how to add a hyperlink to the attachment so when user click the hyperlink the file will be download to disc.
I means that I want to add a hyperlink to the attachment,the hyperlink will get the file's path in mail server.Because the mail's attachment are stored in mail server so I don't know how to get it in my servlet.
what I can do is get a inputstream using messagePart.getInputStream();. I only can get a inputstream in servlet.Ｈｏｗ to change the inputstream to a File when user click it and download it?
Help!
Thks

I am making a same application now...
You have 2 possibilities:
1. Save all the data from the stream to a file That is accessible from the outside through HTTP and then put a link to it
2. Make a link to a seperate JSP page with the following parameters: Folder name (describing where the desired message is), Message id (the number of the message inside the folder) and Part number (you will have to count it yourself). The JSP page then returns all the data.
If you do the second thing, you will have to take care that the first line in the jsp starts with <% because if it does not, the JSP will send an \r\n and that will modify the data.
You will also have to do the following:
response.setHeader("Content-Disposition", "attachment; filename=myfile.txt");
response.setContentType("application/octet-stream; name=myfile.txt");If you know the MIME type, replace application/octet-stream with the MIME type.

How to deal with 500 Servlet Exception ?

500 Servlet Exception
Resin can't load sun.tools.javac.Main. Usually this means that the JDK tools.jar is missing from the classpath, possibly because of using a JRE instead of the JDK. You can either add tools.jar to the classpath or change the compiler to an external one with <java compiler='javac'/> or jikes.
java.lang.ClassNotFoundException: sun.tools.javac.Main
Resin 2.0.4 (built Thu Nov 15 17:56:24 PST 2001)
get these messages(win98,apache1.3,jdk1.3,resin2.0)
how to add tool.jar to the classpath?please detail.thanks!!

Hi,
You can just give a search for the directory contains the file tools.jar. And add the classpath like this
SET CLASSPATH=c:\jdk1.3\lib\tools.jar
You can double check the CLASSPATH in command prompt like this
echo %CLASSPATH%
If the CLASSPATH is set properly, you should see the tools.jar file in the CLASSPATH.
Hope this helps.
Best Luck!
